Technical Overview of the C1117-4PLTEEA
The C1117-4PLTEEA is a Cisco Industrial LTE Gateway designed for enterprises requiring uninterrupted connectivity in remote or mobile environments. It features quad LTE-Advanced (4G) modems, 4x Gigabit Ethernet ports with PoE+, and Cisco SD-WAN integration, ensuring seamless failover between cellular carriers and terrestrial networks. Built to IP67 and MIL-STD-810G standards, it operates in extreme conditions (-40°C to 75°C) and resists shock, vibration, and humidity.
Core Features Driving Network Resilience
- Quad LTE-A Modems: Supports 4x carrier aggregation for up to 450Mbps download speeds and automatic switching between providers to prevent downtime.
- PoE+ Power Delivery: Supplies 30W per port across all 4 Ethernet ports, ideal for IP cameras, wireless APs, or IoT sensors in harsh locations.
- Cisco SD-WAN Integration: Enables application-aware routing, dynamic path selection, and zero-touch provisioning for simplified multi-cloud access.
- Advanced Security: Combines IPsec VPN, Cisco Umbrella DNS-layer protection, and HTTPS/SSL decryption to safeguard data in transit.
Key Use Cases and Industry Applications
The C1117-4PLTEEA is critical for:
- Utilities and Smart Grids: Provides cellular backup for SCADA systems during fiber outages, ensuring real-time grid monitoring.
- Public Safety Networks: Powers mobile command centers with reliable LTE failover for mission-critical communications.
- Mining and Construction: Connects autonomous vehicles and drilling equipment in areas lacking wired infrastructure.

C1117-4PLTEEA vs. C1113-8P: Strategic Differences
| Feature | C1117-4PLTEEA | C1113-8P |
|---|---|---|
| LTE Modems | Quad LTE-A | Dual LTE-A |
| PoE Ports | 4x PoE+ | 8x PoE+ |
| SD-WAN Support | Native Integration | Requires additional licenses |
| Target Deployment | High-failover scenarios | High-density PoE environments |
Why This Gateway Redefines Connectivity Reliability
Having deployed LTE gateways in disaster recovery scenarios, the C1117-4PLTEEA’s quad-modem design is a revelation. Traditional dual-modem models like the C1113-8P struggle in regions with fragmented carrier coverage—switching delays cause hiccups in video surveillance or telemetry streams. This gateway’s 450Mbps throughput and SD-WAN integration ensure applications like VoIP or live sensor analytics never miss a beat, even during network chaos. Companies prioritizing uptime over cost savings will find this investment pays dividends when terrestrial networks inevitably falter. In an era where downtime equals revenue loss, the C1117-4PLTEEA isn’t optional—it’s essential.
